Psycho History

Filed under: General — Tags: — m759 @ 6:00 PM

The title was suggested by the term “psychohistory” in
the Foundation  novels of Isaac Asimov. See the previous post.

See also a 2010 New York Times  review of
DeLillo’s novel Point Omega . The review is titled,
without any other reference to L’Engle’s classic tale
of the same name, “A Wrinkle in Time.”

A Prime Radiant for Krugman

Filed under: General — Tags: , — m759 @ 6:00 AM

Paul Krugman:
Asimov’s Foundation  novels grounded my economics

In the Foundation  novels of Isaac Asimov

“The Prime Radiant can be adjusted to your mind, and all
corrections and additions can be made through mental rapport.
There will be nothing to indicate that the correction or addition
is yours. In all the history of the Plan there has been no
personalization. It is rather a creation of all of us together.
Do you understand?”

“Yes, Speaker!”

— Isaac Asimov, Second Foundation , Ch. 8: Seldon’s Plan

Before time began, there was the Cube.

Core

Filed under: General,Geometry — Tags: , — m759 @ 12:00 PM

Promotional description of a new book:

“Like Gödel, Escher, Bach  before it, Surfaces and Essences  will profoundly enrich our understanding of our own minds. By plunging the reader into an extraordinary variety of colorful situations involving language, thought, and memory, by revealing bit by bit the constantly churning cognitive mechanisms normally completely hidden from view, and by discovering in them one central, invariant core— the incessant, unconscious quest for strong analogical links to past experiences— this book puts forth a radical and deeply surprising new vision of the act of thinking.”

“Like Gödel, Escher, Bach  before it….”

Or like Metamagical Themas .

Galois vs. Rubik

(Continued from Abel Prize, August 26)

The situation is rather different when the
underlying Galois field has two rather than
three elements… See Galois Geometry.
